I am a new owner of a Rachael and a ZP3.  I am on the Decware "list" for buying a CSP3 (down the road).

I think I will buy a preamp for the time being to experiment with.  Someone I know suggested a "Reference Line Preeminence 1B Passive Pre amp".  It's relatively inexpensive.

Has anyone used one for these with a Decware amp?

any thoughts on this would be appreciated!

Thanks!
